To all whom it may concern:

Be it known that I, Jorm A; HANDEL, a; citizen of the United States, residing at Bcloit, in the county of Rock and State of Wisconsin, haveinvented certain newand useful Improvements-1n Rotation Indicators for \Vringer Rolls, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to wringer rolls such as are used on the power operated wringers oflaundries.

In all laundries known to me, plain white wringer rolls are used which operate at a relatively high speed and because of the fact that the wringer roll is a dead white it is practically impossible to see whether the wringer roll is rotated or not. Long experience has proven that with a plain white wr-inger roll the operator many .times forgets that the-rolls have been left in-motion because of the plain'white surface and the lack of light in the laundry and is very apt to place her hands against the rollsand receive severe injury by her hands being drawn inbetwe'en the rolls and "crushed.

The object of the present invention is to so form the wringer roll that it will be obviouswhether the wringer roll .is rotating or not, and generally speaking this is effected by providing the wringer roll designed in a contrasting color to the color of the wringcr roll which will show plainly that the roll is moving. This is best effected by having a color design on the rolls themselves in which the design is ofsuch character that lines are formed which extend diagonally to the length of the roll and preferably lines of contrasting color to each other and to the wringer roll which extend'in opposite diso as to define a series of squares.

In the drawings I have illustrated a wringer roll having such a design thereon,

and inthese drawr'n'gs:- y .Figure 1 is an elevation of a wrmger roll having a design thereon in accordance with my invention;

Figure 2 is a like view to Figure 1, but showing another form of design for the wrin rer roll.

Re erring to these drawings, it will be seen that the wringer roll 10 is of precisely the same construction as ordinarily found in all wringer rolls and is'made of precisely show clearly. merge so as. to give a uniform tone to the 1924. Serial No. 724,068.

the same material. Such wringer rolls are usually made of a rubber having a more or less dead white surface without any markings. My improved wringer roll also may have a dead-white surface such as that of the ordinary w ringer roll, but extending across the surface'of the roll diagonallywith relation to the longitudinal axis thereof and diagonally with relation to the plane of rotation of the roll are a plurality of lines 11 and 12, the lines 11 being blue, for instance, and the lines 12 being red, for instance. The blue lines cross each other at intervals and also cross the red lines, and the red lines. cross each other at intervals and cross the blue lines so that a checker board pattern, as it may be termed, or plaid pattern is produced upon the surface of the roll. If these lines ran parallel to the axis of the roll or if these lines ran at right angles to the axis of the roll, they would not The parallel lines would roll and the circumferential lines would simply show as circumferential bands without indicating any movement and would have no different effect whether the roll were rotating or not, but by makingdiagonal lines of any character whatsoever the rotation of the roll will be made obvious,

\Vhile I have illustrated a roll having relatively thin narrow lines extending diagonally around the roll, I do notwish to be limited to this as these lines might be dots, for instance, or any other made up of or unit which would give design element the effect of a diagonal lines extendingfa t right angles to each other. It will be obvious that the roll might be made of some'other color than ,white and yet havethereon a design in a contrasting color which would show. that the roll was rotating and it is within'the purview of my invention to use a design of this character on a roll of this character.

I claim A rotation indicating wringer roll hava portion of which mg a peripheral face, is of a uniform color, portion of a contrasting color to that of the first mentioned portion:

In testimony whereof I hereunto affix my signature.
